Let’s see......650 miles in 10 days = 65 miles a day @ 4/5 mph = 13/16 hours a day of walking. And she’s 50 and (according to her) not in the best of health. Nope, can’t be done - especially in the deep south in the fat of summer.
I’m not sure there’s anybody on the planet who could do 650 miles in 10 days on foot. It would be quite a workout on a bike, for that matter.
Okay, it turns out the world record for 1000 miles is 12 days, 20 hours; so there are a few people out there who can do 650 miles in 10 days.
However, I bet the above record wasn’t set in the American South during July!
